资源说明:This plugin add Internet Archive BookReader (http://openlibrary.org/dev/docs/bookreader) into Omeka.
BookReader (plugin for Omeka) ============================= [BookReader] is a plugin for [Omeka] that adds [Internet Archive BookReader]. The IA BookReader is used to view books from the Internet Archive online and can also be used to view other books. So you can create online flip book from image files constituting an item or from files listed in a gDoc spreadsheet. See demo of the [embedded version] of [Mines ParisTech] or in [fullscreen mode] with highlighted results of a search in the OCR text ([Université Rennes 2]). For the spreasheet use, see [gDoc explanation]. The javascript included comes from [BookReader spreadsheet] via [Dušan Ranđelović fork]. Main benefit is that item doesn't need to have all pages/images uploaded to Omeka and that there is no need for composit PDF, so presentation is completely parted from metadata. Installation ------------ - Upload the BookReader plugin folder into your plugins folder on the server; - Activate it from the admin dashboad > Settings > Plugins page - Click the Configure link to add the following - Name of to custom class (default is `BookReader_Creator_Default`) - Sorting mode for the viewer (omeka default order or original filename order) - Number of pages in Embed mode (1 or 2) - Embed all functions (0 for none or 1 for all) - The width of the inline frame (Embedded Simple Viewer) - The height of the inline frame (Embedded Simple Viewer) If you want to change more options, copy the file `views/public/viewer/show.php` in the subdirectory `book-reader/viewer/`of your theme and update it. See below the notes for more info. Usage ----- The viewer is always available at `http://www.example.com/items/viewer/{item id}`. Furthermore, it is automatically embedded in items/show page. This can be disabled in the config of the plugin. The url for the default page `items/viewer/:id` can be replaced by the old one `viewer/show/:id` or any other url via the file `routes.ini`. To embed the BookReader with more control, three mechanisms are provided. So, according to your needs, you may add this code in the `items/show.php` file of your theme or anywhere else, as long as the item is defined (as variable or as current record 'item'). * Helper (recommended) - With no option: ``` echo $this->getBookReader(); ``` * Shortcode - In a field that can be shortcoded: `[bookreader]`. - Default in theme: `shortcodes('[bookreader]'); ?>` - With all options: ``` shortcodes('[bookreader item=1 page=0 embed_functions=0 mode_page=1]'); ?> ``` * Hook - With all options: ``` true, 'view' => $this, 'item' => $item, 'page' => '0', 'embed_functions' => false, 'mode_page' => 1, )); ?> ``` All options are optional. If one is not defined, the parameters set in the config page will be used. The image number starts from '0' with default functions. Notes ----- - A batch edit is provided to sort images before other files (pdf, xml...) that are associated to an item (Items > check box items > edit button). *Warning* PHP should be installed with the extension "exif" in order to get the size of images. This is the case for all major distributions and providers. If technical metadata are missing for some images, in particular when the extension "exif" is not installed or when images are not fully compliant with the standards, they should be rebuilt. A notice is added in the error log. A form in the batch edit can be used to process them automatically: check the items in the "admin/items/browse" view, then click the button "Edit", then the checkbox "Rebuild metadata when missing". The viewer will work without these metadata, but the display will be slower. Customing --------- There are several ways to store data about items in Omeka, so the BookReader can be customized via a class that extends `BookReader_Creator`. BookReader uses several arrays to get images and infos about them. Take a document of twelve pages as an example. In Javascript, we have these arrays: - br.leafMap : mapping of pages, as [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11] - br.pageNums : number of pages, as [,, "i", "ii", "iii", "iv", 1, 2, 3, 4, 5,] - br.pageLabels : label of pages, as ["Cover", "Blank",,,,, "Page 1 (unnumbered)",,,,, "Back cover"] - br.pageWidths : width of each image, as [500, 500, 500, 500, 500, 500, 500, 500, 500, 500, 500, 500] - br.pageHeights : height of each image, as [800, 800, 800, 800, 800, 800, 800, 800, 800, 800, 800, 800] With the default files of BookReader, all images of an item are displayed, so the leafMap indexes are always a simple list of numbers like above (starting from 0 when the first page is a right page, else from 1). Page numbers and/or page labels can be empty, so in that case the index is used. When the user leafs through the document, the viewer sends a request with index + 1 as image parameter. So the controller can send the index - 1 to select image in the ordered list of images files. Some functions of php are used to make relation with this index and to provide images. They are used in the beginning and via Ajax. During creation of the viewer, php should provide mapping, numbers and labels via BookReader custom functions (`getPageIndexes()`, `getPageNumbers()` and `getPageLabels()`). These functions use one main method, `getLeaves()`, that provides the ordered list of all images that should be displayed as leaves (saved by default as a static variable in php). This list is used too to get the selected image when needed via the index. The `getNonLeaves()` method is used to get links to other files to share. So,The list of leaves files is a simple array as [File 1, File 2, File 3, File 4...]. In case of a non-digitalized blank or forgotten page, in order to keep the left/right succession of leafs, the mapping and the page numbers and labels should be the same, and the list of leaves files should be [File 1, null, File 3, File 4...]. The `transparent.png` image will be displayed if an image is missing, with the width and the height of the first page. In case of multiple files for the same page, for example with a pop-up or with and without a tracing paper, the mapping can be: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 9, 12, 11]. Other arrays should be set in accordance: number of pages as [,, "i", "ii", "iii", "iv", 1, 2, 3, 4, 5, 4, 5,], labels as ["Cover", "Blank",,,,, "Page 1 (unnumbered)",,,, "Page 5 with tracing paper", "Back cover"] and files as [File 1, null, File 3, File 4..., File 10, File 11a, File 10, File 11b, File 12]. Any other arrangements can be used. To avoid to calculate these data each time an item is displayed, it's recommanded to save them either in a xml file, or in the database. It's specially important for widths and heights data, as all of them should be got before first display. A batch can be launched in the admin/items/show page if needed. The function `saveData()` should be customized to your needs. Of course, other functions should check if these data are available and use them. This function can be used too the first time a viewer is displayed for an item. Spreadsheet use --------------- To test it, create an item with this value in Dublin Core : Relation: `https://spreadsheets.google.com/feeds/list/0Ag7PrlWT3aWadDdVODJLVUs0a1AtUVlUWlhnXzdwcGc/od6/public/values`. This is the public Atom feed of a Google Spreadsheet with five columns. These columns are `image`, `height`, `width`,`num` and `label`. Only the first one, that is the url to the image, is required. See [gDoc explanation] for more info. Then go to `http://example.org/items/view/{item id}`. Remarks: - Because data are not in the local database, the build of the Book Reader can take some seconds when the page is loaded. - Thumbs are not set because files are not in database but on custom server place listed in gDoc. - In the default example, the image 182 is set in the spreadsheet, but is empty. Optional plugins ---------------- The extract ocr and pdfToc plugins are highly recommended. - [Extract ocr] allows fulltext searching inside a flip book. To enable it in BookReader, you need to overwrite Bookreader/libraries/BookReader/Creator/Default.php using Bookreader/libraries/BookReader/Creator/ExtractOCR.php or to set the path in configuration panel of the extension. - [PDF Toc] retrieves table of contents from pdf file associated to an item.
